Wash Down

Wash down cleaning methods are appropriate for cleaning the robot. Surfaces and joints have
been designed with smooth internal radii for easy cleaning.
NOTE: The following cleaning actions and intervals are suggestions only. Refer
to HACCP guidelines to determine what is required for your installation.

Water Shedding

Surfaces of the robot have been designed to shed water. This increases the likelihood that con-
taminants or cleaning agents will drain with a wash-down procedure.

Design Factors

Environmental and cleaning aspects are addressed by the following features in the iX4-
650H/800H robots.
Robot Base and Components
The aluminum robot base and the removable motor covers are coated with a polyurethane
powder coating, which will not flake off with repeated high-pressure washings. This coating is
resistant to caustic and chlorinated agents, has strong adherence to the metal base to resist
impact, and has a smooth finish that is easy to clean.
The gearboxes are sealed internally, and sealed externally by a lip seal that is designed to meet
IP65 rating.
All base seal materials are designed to be compatible with caustic agents and common indus-
trial cleaning procedures.
!
The motor cover seals allow for periodic motor and fan inspections.
Inner Arms
The inner arms are painted aluminum. The assemblies are resistant to some caustic cleaning
agents at room temperature, as well as to chipping.

CAUTION: PROPERTY DAMAGE RISK
Like most seals, it is possible to prematurely destroy these seals by deliberate,
direct, excessive spraying of water-based agents into the sealing materials.
